Chloromethane, also known as methyl chloride, HCC-40 or R-40 belongs to a group of organic compounds called haloalkanes. It is an extremely flammable colorless gas which is usually detected at toxic levels. Chloromethane is synthesized by boiling a mixture of sodium chloride, sulfuric acid and methanol. Significant amount of chloromethane is produced naturally in the oceans by the action of sunlight on chlorine and biomass in sea foam. It is majorly used in manufacturing silicone polymers, butyl rubber and in petroleum refining. Chloromethane was initially used as a refrigerant, but was discontinued on account of its flammability and toxicity. Due to its substantial toxic effects, it is no longer used in consumer products. Different types of chloromethanes such as methyl chloride, methylene chloride, chloroform, and carbon tetrachloride are produced in the industry. Methyl chloride is the largest segment and is also the most important type of chloromethane, largely used in medical and pharmaceutical industries. In terms of application, the silicone industry is expected to witness the fastest growing application segment over the forecast period due to the rising demand from medical and personal care industries. Moreover, growing household incomes, rising living standards and an ever-expanding middle class in Asia Pacific and Rest of the World (RoW) are contributing to the boost in demand for high quality products containing silicone. China has been the most attractive market in Asia Pacific for chloromethane with a significant potential for massive growth in certain end-user industries such as automotives and pharmaceuticals.
